Does .mapNotNull { … } let you do what you want?

[y]

it does! thanks.\

[Robert Williams]

Surely just doing a null check in the filter block will do the same?

[Sam]

@Robert Williams the disadvantage there is the result is still a List<T?>, not a List<T>

[Robert Williams]

Ah yeah, different return type

But overloading the extension function to also take a predicate shouldn’t be an issue
